20.500.12556/RUL-153055 Fixed and adaptive beamforming improves speech perception in noise in cochlear implant recipients equipped with the MED-EL SONNET audio processor Objective: To determine the impact of the fixed and adaptive beamforming technology of the new MED-EL SONNET cochlear implant audio processor on speech perception in noise. Methods: The study cohort comprises 18 postlingually deafened adult cochlear implant recipients with at least six months of experience. Speech reception thresholds were measured with the Oldenburg Sentence Test in continuous, speech-shaped noise. Target sentences were presented in front of the listener, with noise sources placed at -135° and 135°, respectively. Outcome measures were the differences in speech reception threshold using omnidirectional, fixed and adaptive beamformer microphone settings. Results: The use of directional microphones significantly improved speech reception thresholds: fixed beamformer vs. omnidirectional: 4.3 dB (95%-CI [3.1; 5.5]), p<0.0001; adaptive beamformer vs. omnidirectional: 6.1 dB (95%-CI [4.9; 7.3]), p<0.0001; and adaptive beamformer vs. fixed beamformer: 1.8 dB (95%-CI [0.7; 3.0]), p = 0.001. Conclusion: This study confirms the previously reported improvements in speech perception in noise of the fixed beamformer microphone setting and is the first to report significant improvements in speech perception in noise when applying the adaptive beamformer microphone settings of the SONNET audio processor. Cochlear implant users may be able to benefit from improved hearing performance especially in difficult listening situations. speech perception adaptive beamforming technology fixed beamforming technology cochlear implant MED-EL SONNET cohort study true false true Angleški jezik Angleški jezik Članek v reviji 2023-12-15 10:45:47 2023-12-15 10:45:54 2023-12-16 03:49:05 0000-00-00 00:00:00 2018 0 0 Str. 1-10 no. 1 Vol. 13 2018 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 616.21 1932-6203 10.1371/journal.pone.0190718 177626115 RAZ_Honeder_Clemens_2018.pdf RAZ_Honeder_Clemens_2018.pdf 1 9CE6C4D5FD61B7D02A8D9A4438E3C97F adb2aac3d32986abfec5622f8325a0f08cc94dbfbadc93f2901568cbf5dd32ea d14fdc2c-9b33-11ee-bebf-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=178850 https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0190718 1 be1293dc-9b2e-11ee-bebf-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=178849 Biotehniška fakulteta 0 0 0
